Abstract
Nano materials are undoubtedly one of the versatile materials whose properties hasn’t been much explored yet. Regular efforts are being made to perk up the quality of concrete on various fronts to make it more sustainable. In this work, Nano-silica (Sio2) has been selected to induce it in M30 base mix design and workability test and strength tests has been selected which will be carried out on cube and beam specimens casted and cured for seven, fourteen and twenty eight days of duration. Properties of OPC and nano Silica powder has been note down. Nano silica comes in different surface sizes in market i.e. 50 m2/g, 250 m2/g and 500 m2/g. Current study chose Sio2 having 250 m2/g surface area as was available in local market. Concrete mixes are designed by taking 0.5%, 1%, 1.5% and 2% of Nano-silica with respect to weight of cement. The addition of nano silica proved to be beneficial to the mechanical properties which increased significantly than the base mix .Also workability test showed moderate values of slump which also decreases when Nano-silica proportion is increased.
